but lesser

install

npm install shy-co

version 0.1.2

it's stable

How to Use

'use strict'
let	co=reuqire('shy-co')

co(function*(){
    let x
    x=yield [666,Promise.resolve(6)]
    console.log(x)//log:[666,6]
    x=yield Promise.resolve(6)
    console.log(x)//log:6
    x=yield ()=>7
    console.log(x)//log 7
    x=yield 666
    console.log(x)//log: 666 (ps:return self)
    x=yield Promise.reject(6)
    console.log(x)//not run
}).then(
    null,
    err=>console.log(err)//log:6
)

Advantage

you can yield anything

if you yield x ,it will do yield co(x) ps:Promise>[]>function*>function>value

ES3

//实例
var co = require('shy-co/es3.js')//兼容ie8,但是用法不一致
co(function gen(yield){//名字含有gen的函数会得到一个taskAdd函数作为参数
    yield(function(){
        return 0
    })
    yield(function Promise(val,rj,rj){//名字含有promise的函数会多出两个参数promise构造函数中的resolve,reject
        console.log(val)//log:0
        rl(1)
    })
    yield(function(val){
        console.log(val)//log:1
        throw 2
    },function err(err){//这个函数会被添加到promise中的catch参数中,没有的话错误直接抛出
        console.log(val)//log:2
        return 2
    })
})
